y COOLING-TANK.

'To all w from it may] concern Be it known that I, HERBERTC. FoLLIN- one, av citizen of the` United States, and a resident of Chicago, in the countyy of Cook and Stateof illinois, have invented Vcertain new and useful Improvements in Cooling Tanks,` of whichV the` following kis a" full, clear, andexact specification. s

My .invention is Concerned withl cooling tanks designed for taking hot` cans yfilled with corn` or "other materials as they `come i from the cooker "and cooling them with a minimum oftrouble and expense, and without` the possibility` of. deforming or opening the cans so as possibly` to cause a leakage and ultimately spoil the 'Contents of the cans so deformed. f y y To `this end, it consists of an endless con-` Veyer mounted in a trough kept'supplied with cool waterv and operating so that the hot cans can be dumped into the water and onto one `end of the Continuously movingv conveyer and carried thereby through the length of the trough `and up fout of the cooling water to the point of discharge.`

Toillustrate my inyention,"I annex hereto twosheets of drawings in whichthe same reference characters areeinploy'ed tol desig#` nate identical parts. in fall the figures of whichif `l Figure l is a top plan yiew of a portion of the Cook room of a canning factory having my invention installed therein, a perf tion of the central part of; the apparatus being broken away to shorten the length 'of the View; l i Fig. 2 isa side elevation of the same in section on the line 2-2 of Fig. l;

Fig. 3 is a detail in section` on a larger scale on the line 3 3 of Fig. l;

Fig. 4 isV a similar View but on a .still` larger scaleand looking in the'V opposite direction from Fig. 3 gf 1 Fig. 5 4is aside elevation ofa portion of the mechanism seen Fig; 4,-"but taken yat another point `where the ends of 'two sections 'offthe wooden side-pieces meetyw,`

`Figw is a detail in vertical section on the line 6 6 of Fig. 2; and Y Fig. 7 is side Velevation of the mecha-g nism seen in Fig. 6 as seen from the righthand side of said figure. [l i In the drawings, 1Q representsv the floor of a" portionof vthe cook `room'of a `canning Speccaton of Letters,Patient;r v Patented Juily 12, 1921. applicati@ fried June 1o7 1919. Asenai No. 303,223. i l i factorylof which twoof the wallsll and 12 in which isjournaled the shaft andsprockg etsw-.lyover which the endless conveyer k1T travels. Thisendless conveyer is made up ofa 'plurality of cypress flights l8`of the proper length tospan the width of the trough and hai/ing the links 19 ofthe pair of sprocket, chains `2O connectedv to the un-r der sidestherjeof. `On the upper run, the

having horizontall anges projecting v inwardly from the sides ofthe trough and supported in a manner to be subsequently described. Onthe'retuijn run, theends of the flights,preferablytravel over the angle irons 23 similarly located and supported so as the tanker trough. f

Secure'l` to l the lsides `of the-trough as by the bolts 2e set intothe concrete at suitable interralsare therertical metallic bars 25, tolwhich are riveted the angle irons `22`and `so as` to form "tracks throughout the length ofthe tank, vwhich may be say l0() "feet long, andat the receii/'ing end, the vangle irons 23 are near the bottom. graduallyinclining upward until at the point where G is taken in Cross-section, the

angle irons 22 and 23 are cnrvedto make theffinal portion of the path of the `conyeyer vthrough the trough or Vtank much steeperto morequickly Carry the vcans out of the cooling ,wateigfa constant supply ofy lchain issupportedby lthe angle irons 22,

is secured `belt Wheel 36 by which the power Y Y is supplied. By means o-f the train of re ducing gearing thus described, it will be obvious that the belt 17 1s Acaused to move very slowly through the length ofthe trough so as thoroughly to coolvthe cans and their contents in gthecold Water With which the tankV is filled and finally to carry them out of the tank: and to the positionabove the fioo-r VWherethe cans can be removed manua'llyor shunte'd ontoanother conveyer.

The sides of the tank above theV angle iron 22 are lined bythe boards 37, suitably ses cured to the vertiealpieces 2, 'andfpreferably having their meeting ends cut diag-A onally, as seen in Fig. 5,\vherever a joint Y n ofthe' \vater, itis necessary 'to provide an is necessary. These boardsare J protected against Wear and splintering by the sheet metalfguide{pla-tes 38 secured `on the; face of the' boards 37;*by any suitabl-emeans, such asthe screws1397-these guide plates prefer-p ably having their upper ends 40 inclined over to contact with the walls ofthelta'nk. It: Will be noted thatthe edges of the conveyerru-n directly under the boards 37, so as p to insure the cans :being Wholly supportedfby the conveyer. e l

At the point Where the inclinationorthe conveyer is increasedV tolift the Acans out abutmentftol hold dewyn thefupper surface of the conv'eyer 17 at its edgesyan'd for this Y purpose, I preferably :employ the flanged rollers 41, which coperatevvith the edges of the conveyer 17, the body of the periphery contacting with the top of the edge of they conveyer, While vthe flanges'ext'end below said the'reoiv the verticall recesses 42 in which are top, as seen in Fig. 6. To support properly these flanged rollers 41 Without causing themv to project substantially into the body of the tank or trough, -I provide in the Walls secured the bars 43, which in turn support the bearing studs 44 for the rollersg41. rIhe Y boards 37 are cut away at the points Where rollers 41.` y Y Y v Y t y Y lith theconstruction described, it will be obvious that if the cans filled with the hot,V

the ,rollers `41- are fonnd,butl the guide plates 38V are-continued across the gap and extend down over the'upper part of the ,just cooked, Vcontents are dumpedintorthe tan-kbeyond the enlarged 'end 14, they Will settlefdoivn on the constantly moving `conve'yler andwill be carried 'thereby Without anydisplacement relative to eachother or to theconveyer throughout the entire length of the ltank, as there is no place Where there is any contraction of the passageway,.and

they Will eventually be delivered out of:

the tank and ydling. Y Y p While I have shown and described. my invention as embodied in the form which I at cooled ready for further hann .present consider best adapted to carry out its purpose, it ivilljbe understood that it is capable of some modifications and that -I Vdonot desire to be limited in the interpretation Aof the following claims except as may .be necessitated by the state .ofthe prior art. What Iclaim as lnew and desire to secure by Letters Patent of the United States is:

1. In a cooling tank, the combinationwith a trough having the sides slightly over# hanging the `edges of' the bottom, of end-- less conveyer therein with its. edgesA on itsV j upper run traveling underneath andAV adjacent said overhanging'sides `longitudinal supports' for' the edges "of said conveyer onV its'rupp'er run, rotating memberssupporting the conveyer atfthel ends of the trough, one off.- said members being abovefthe planeV of the top of the trough, means for driving 'the conveyed and an abutment'on each sidefof the tro-ugh extending over the edges of the belt on its upper' run` but notbeyond the vertical plane of the overhanging sides, andV located at theV point Where the top 'run of" Y the conveyer turns! upward to carry the cans the top of the trough, means iojr driving the conveyer and a. guide roller oneach'side of the; trough jeurnaled therein'so that its pe-V riphery extendsover the edge or' the con- 11o Vveyer on its upperv run but not beyond the vertical plane of the overhanging sides. and

locatedkatV the point Where the top run of the conveyer turns upward to carry thefcans out of they Water.

3, In a cooling tank, the combination A `With a trough having the sides provided with vvooden strips secured thereto'andrhaving a metallic sheathing over'and secured to said strips and slightly overhanging the edges of the bottom,'of an endless conveyor therein with its edges on its upperrun traveling underneath l and adjacent said overhanging s'ides,lengitudinal supports forl the edges of the conveyer on itsrupper. run, ro`

tating members supporting thejpbelt at the ends of the trough, one of saidmembers being above the plane of thetop of the trough, Vvmeans for driving the conveyenand an abut'- ment on each side of thegtro'ugh directly over the edges of the conveyer on its upper run but not beyond the vertical plane of the metallic sheathing' and located at the point Where the top run of the conveyer turns upward to carry the cans out of the Water.

4L. The combinationlwith a tank, of vertically disposed supporting bars secured to the sides of the tank, rails supported by the said bars for the upper and lower runs respectively of an endless conveyer, lining strips for the tanks secured against the said vertical bars and arranged to be substantially parallel with and` to somewhat ovel- I hang the rails for the upper runs of thev conveyer, and an endless conveyer having a flat carryn surface Without marginal edges adapted to e supported, near its edges, by the said rails, 'and the supporting surface thereof extending under the overhanging lining strips. y

In Witness whereof, I have hereunto set niy hand and affixed my seal, this 20th day of May, A. D. 1919.
